Abstract

Amphiphilic silicons which are dispersible or self-dispersing in water, have a high refractive index, and are prepared by a hydrosilylation reaction, resulting in products which are free of cyclic organopolysiloxanes. The high refractive index and dispersibility make the amphiphilic silicones useful in personal care and cosmetics where high shine or gloss is desired.
